Core Viewpoint - Innovent Biologics (01801.HK) announced that its drug, IBI310 (Ipilimumab N01 injection), has been approved by the National Medical Products Administration (NMPA) in China for use in neoadjuvant therapy for resectable stage IIB-III microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) colorectal cancer patients when combined with Sintilimab [1] Group 1 - IBI310 is the first domestically approved anti-CTLA-4 monoclonal antibody in China [1] - It is also the first anti-CTLA-4 monoclonal antibody globally approved for neoadjuvant therapy in colorectal cancer [1] - The combination therapy significantly improves the pathological complete response rate for MSI-H/dMMR colorectal cancer patients [1]

Core Viewpoint - The National Medical Products Administration (NMPA) has approved the launch of the anti-CTLA-4 monoclonal antibody, Ipilimumab N01 injection (brand name: Daberxin), developed by Innovent Biologics, for neoadjuvant treatment in patients with resectable stage IIB-III microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) colorectal cancer, marking it as China's first domestically approved anti-CTLA-4 monoclonal antibody and the first globally for this indication [1][5]. Group 1 - The approval is based on the results of a randomized, controlled, multi-center Phase III registration study (NeoShot-III, NCT05890742) conducted in China, which aimed to evaluate the efficacy and safety of Ipilimumab N01 in combination with Sintilimab compared to direct radical surgery [3][7]. - The primary endpoints of the study included pathological complete response (pCR) and event-free survival (EFS) [3][7]. - The interim analysis of the NeoShot-III study showed that the predefined primary endpoints were met, as assessed by the Independent Data Monitoring Committee (iDMC) [3][7]. Group 2 - As of November 28, 2024, among the first 50 patients in the trial group, 41 achieved pathological complete response after neoadjuvant treatment, resulting in a pCR rate of 82% [4][8]. - In terms of safety, the combination of Ipilimumab N01 and Sintilimab did not significantly increase additional safety risks compared to the direct surgery group [4][8]. - The Chief R&D Officer of Innovent Biologics, Dr. Zhou Hui, emphasized the significant unmet clinical need for neoadjuvant treatment in resectable MSI-H/dMMR colorectal cancer, highlighting the importance of the NeoShot-III study's interim analysis for this treatment area [4][8].
